Description

Technical Field

[0001] The invention relates to the technical field of pressure control, in particular to an anaerobic environment pressure balancing device. Background Art

[0002] The feeding, discharging and reaction process in the anaerobic reaction container will cause changes in the pressure in the container. At present, a rubber sheet-type deformation sheet is usually set to adapt to the changes in the pressure in the container through its deformation. This structure is sufficient for reactions in smaller containers with manual intervention, but for larger reaction vessels in continuous production, automatic feeding and discharging require less manual participation, and the reaction container needs to be in a closed state during the reaction process. At the same time, a large amount of material will often be added and discharged within a period of time during the material feeding and discharging process, which requires the reactor to discharge or inhale a large amount of gas in a short time, but there is currently a lack of such devices to meet the needs of continuous production of reactors.

DETAILED DESCRIPTION

[0025] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0026] A specific embodiment of the present invention provides an anaerobic environment pressure balance device, whose main structure is a accommodating chamber, which is filled with liquid. The liquid can be water or disinfectant, etc. The accommodating chamber is divided into a first cavity 1, a second cavity 2 and a third cavity 3, and the first cavity 1, the second cavity 2 and the third cavity 3 are distributed in the horizontal direction. At the same time, the bottoms of the first cavity 1, the second cavity 2 and the third cavity 3 are interconnected to ensure the circulation of liquid and gas, and a first connecting port 4 is arranged on the first cavity 1, a second connecting port 5 is arranged on the second cavity 2, and a third connecting port 6 and a fourth connecting port 7 are arranged on the third cavity 3. A one-way valve 8 is arranged on the third connecting port 6 and the fourth connecting port 7, and the air inlet end of the one-way valve 8 is connected to ensure that the gas in the third cavity 3 can be discharged in one direction and ensure that the gas cannot enter the third cavity 3 from the outside through the third connecting port 6 and the fourth connecting port 7.

[0027] In actual use, the anaerobic environment pressure balance device of the above-mentioned structure requires that one of the first connecting port 4 and the second connecting port 5 be connected to the reaction container, and the other be connected to the external air pressure zone, and one of the third connecting port 6 and the fourth connecting port 7 be connected to the reaction container, and the other be connected to the external air pressure zone; in the specific embodiment of the present application, the first connecting port 4 and the third connecting port 6 can be connected to the external air pressure zone, and the external air pressure zone can be the atmospheric environment or a filter or other device connected to the atmosphere, and the filter or other device can filter the gas entering the reaction container and the gas discharged from the reaction container; the second connecting port 5 and the fourth connecting port 7 are both connected to the reaction container.

[0028] The anaerobic environment pressure balance device provided in this application can achieve the following Figure 2 The positive pressure exhaust effect in the reaction container shown in the figure can also achieve the following Figure 3 As shown in the figure, the exhaust of the reaction container occurs during the feeding and reaction process before the reaction in the reaction container. During the feeding, a large amount of material will be added to the reaction container within a period of time. At this time, the air pressure in the reaction container will increase rapidly. At this time, the gas will push the liquid in the second cavity 2 down. When the liquid level drops to the position where the first cavity 1 and the third cavity 3 are connected, the gas will form bubbles and enter the third cavity 3, and then be discharged from the third connecting port 6 at the top of the third cavity 3. During the reaction process in the reaction container, other gases will be continuously generated, which will also increase the air pressure in the reaction container. Similarly, the increase in air pressure will push the liquid level in the second cavity 2 down. On the contrary, when the reaction container discharges materials, negative pressure will be generated inside the reaction container. At this time, due to the atmospheric pressure, the following will be generated Figure 3 As shown in the gas flow direction, the gas will enter from the first connecting port 4, and then push the liquid level in the first cavity 1 to drop. When the liquid level in the first cavity 1 drops to the position connected with the third cavity 3, the liquid level will no longer drop. At this time, the gas will enter the third cavity 3 in the form of bubbles, and then enter the reaction container from the fourth connecting port 7.

[0029] By connecting the above-mentioned anaerobic environment pressure balance device to the anaerobic reaction container, gas exchange between the reaction container and the external air pressure zone can be achieved, and at the same time, the precise pressure control function during the reaction can be met. The pressure control principle is achieved through the height of the liquid level in the second cavity 2 under normal conditions. Exhaust will only be formed when the internal pressure of the reaction container can completely push the liquid level of the second cavity 2 down to the connection with the third cavity 3. At this time, the liquid level difference between the second cavity 2 and the third cavity 3 can be used to calculate the maximum pressure value in the reaction container. Conversely, the maximum pressure value in the reaction container can be controlled by controlling the amount of liquid added to the containing cavity.

[0030] In a specific embodiment of the present application, the first cavity 1 and the second cavity 2 are arranged on both sides of the third cavity 3. Such an arrangement can ensure to the greatest extent that most of the gas is discharged from the second cavity 2 through the third cavity 3 when the reaction container is exhausted, and can also ensure that most of the gas enters the reaction container from the first cavity 1 through the third cavity 3 when the reaction container is inhaled.

[0031] In the present application, the first cavity 1, the second cavity 2 and the third cavity 3 are all straight-cylindrical cavities, that is, the containing cavity is set to a straight-cylindrical structure, which can be a cylindrical or square cylinder structure, and the first cavity 1 and the second cavity 2 can be straight-cylindrical structures arranged in the containing cavity. In the present application, the volume of the first cavity 1 can be equal to the volume of the second cavity 2, and the volume of the third cavity 3 can account for more than sixty percent of the total volume of the containing cavity. The way in which the third cavity 3 occupies a larger volume ratio can ensure that after the liquid levels of the first cavity 1 and the second cavity 2 drop to the lowest, the overall liquid level of the containing cavity will not be too high. If the third cavity 3 occupies a smaller proportion, the containing cavity as a whole needs to have a larger upper space to accommodate the liquid discharged from the first cavity 1 or the second cavity 2. At this time, if a deeper liquid level is still needed to ensure a higher pressure in the reaction chamber, it is necessary to increase the height of the overall containing cavity, which causes the anaerobic environment pressure balance device to be too high as a whole, thereby occupying a larger space.

[0032] The anaerobic environment pressure balance device provided in the present application can be a device that has two partition walls 9 arranged inside the receiving chamber, and the receiving chamber is divided into a first cavity 1, a second cavity 2 and a third cavity 3 by the two partition walls 9. A flow gap 10 is left between the bottom of the partition wall 9 and the bottom wall of the receiving chamber. The flow gap 10 can ensure the circulation of liquid and gas, and the liquid level is higher than the bottom of the partition wall 9.

[0033] The first communication port 4, the second communication port 5, the third communication port 6 and the fourth communication port 7 of the present application are all arranged on the top wall of the accommodation cavity, and the material of the accommodation cavity can also be selected from transparent materials for easy observation, as shown in the attached Figure 5 As shown, a vertical scale 11 may also be provided on the partition wall 9 for calculating the liquid level difference.

[0034] Combined with Figure 4 An ultraviolet disinfection lamp 12 can also be arranged in the accommodating cavity. The ultraviolet disinfection lamp 12 is used to disinfect the internal liquid and gas. The ultraviolet disinfection lamp 12 can be arranged on each inner wall of the first cavity 1, the second cavity 2 and the third cavity 3. By arranging the ultraviolet disinfection lamp 12, the disinfection of the gas entering the reaction container can be ensured, thereby ensuring the reaction in the reaction container.

[0035] It is worth noting that the anaerobic environment pressure balance device provided in the present application does not require any external energy source when the ultraviolet disinfection lamp 12 is not provided, and has strong versatility.

[0036] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
